Description Janet 2010-12-19 19:10:05 UTC

Version:           unspecified (using KDE 4.5.85) 
OS:                Linux

When I want to take a region snapshot of my desktop the ksnapshot window does not hide, so that I have to place it where it does not cover what I want to capture befor I take the shot. When I want to take a region snapshot of some application window the ksnapshot window hides but leaves a solid grey rectangle in the size of its window on the other application window so that I have the same problem.

Reproducible: Always




OS: Linux (i686) release 2.6.35-24-generic
Compiler: cc

Hi,

Still there with KDE-4.6.5. 
Please note that it *might* work after several repeated attempts -- f.i. hitting "Take New Snapshot" button, or Alt-N + ESC until the control window hopefully disappears. 
Interestingly, the success probability seems to depend on the percentage of screen covered by windows and by their "type" (native or non-KDE/QT):
- no window (only background): >90%
- partial coverage by one/more windows: 30-60%
- full screen/maximized windows: <10%
Scenarios (one app window only):
- SeaMonkey (GTK-based): 
  * maximized: works ~0%
  * partial: works sometimes
- okular (QT-based): 
  * maximized: works ~100%
  * partial: works 80-90%
- konsole (QT-based):
  * maximized: works 80-90%
  * partial: works 50-80%

I also observe an increasing failure rate with partial coverage: after 2-3 good attempts, it starts failing repeatedly until KS is killed and relaunched.

HTH!

I have this problem only when 3d effects are disabled.

For me the fix was to disable Fade. System Settings > Desktop Effects > All Effects > Fade (Make windows smoothly fade in and out when they are slowly shown or hidden.)

Comment 7 Christoph Feck 2014-04-15 14:38:08 UTC

Not sure if this is a duplicate, because comment #3 / comment #4 says it is reproducible without compositing.

If someone can still reproduce, please add a comment or reopen.

@ro.ggi@gmx.de: is this still an issue with a more recent KDE version? Do you still have the problem with desktop  effects disabled?

Comment 9 Janet 2014-04-15 19:02:43 UTC

For me it is solved. The window does dissappear when I want to capture a region on the desktop and there also is no grey rectangle when I want to capture the region of a window. I have tested it with KDE SC 4.12.4 and effects enabled and disabled. BTW: I never had the problem described in Bug 279615 (semi-transparent ksnapshot window) though I always have the fade effect enabled.
